From the end of the Stone Age onwards, wherever suitable clay was to be found, the potter plied his trade. The Romans, who had brought the art of potting to a high pitch of excellence, introduced improved methods into Britain, where numerous remains of kilns and innumerable fragments of pottery testify to the industry and the individuality of the Romano-British potters. Several quite distinct types of pottery have been identified, and are assignable to definite localities. Great quantities of black and grey wares, consisting of articles of common domestic use, ornamented for the most part only with broad bands of darker or lighter shading, were made in Kent near the Medway, the finer specimens being associated with Upchurch.1 From the potteries in the New Forest 2 came vases of greater ornamental and artistic execution, but it was the neighbourhood of Castor in Northamptonshire that occupied in Roman times the place held in recent times by Staffordshire.
